To enable boil-off gas in a gas phase separated from re-liquefied boil-off gas in a gas-liquid mixed state to be appropriately combusted by supplying the same to a desired device.SOLUTION: A boil-off gas processing system 4 comprises: a boiler 15 which can combust boil-off gas generated in a tank 3 where LNG is stored and produces steam: a re-liquefying device 13 which performs liquefaction process of the boil-off gas generated in the tank 3; a gas-liquid separator 14 which separates the boil-off gas in a gas-liquid mixed state after undergoing the liquefaction process in the re-liquefying device 13 into the boil-off gas in a gas phase and the boil-off gas in a liquid phase; a flow passage which guides the boil-off gas in the gas phase separated with the gas-liquid separator 14 to a main engine 2; another flow passage which guides the boil-off gas in the gas phase separated with the gas-liquid separator 14 to the boiler 15; and a first valve 19a, a second valve 33a and a third valve 36a which switch destinations of the boil-off gas in the gas phase separated with the gas-liquid separator 14 between the main engine 2 and the boiler 15.SELECTED DRAWING: Figure 1

    【課題】再液化された気液混合状態のボイルオフガスから分離された気相のボイルオフガスを所望の装置へ供給することで、好適に燃焼させることを目的とする。【解決手段】ボイルオフガス処理システム4は、LNGが貯留されているタンク3で発生したボイルオフガスを燃焼可能であって蒸気を生成するボイラ15と、タンク3で発生したボイルオフガスに対して液化処理を行う再液化装置13と、再液化装置13で液化処理が行なわれた気液混合状態のボイルオフガスを気相と液相とに分離する気液分離器14と、気液分離器14で分離された気相のボイルオフガスを主機用エンジン2へ導く流路と、気液分離器14で分離された気相のボイルオフガスをボイラ15へ導く流路と、気液分離器14で分離された気相のボイルオフガスを主機用エンジン2へ導くか、ボイラ15へ導くかを切り換える第1バルブ19a、第2バルブ33a及び第3バルブ36aと、を備えている。【選択図】図1
